Rewards

The only 100%-specific reward in GTA IV is the ability to buy an unlimited amount of ammunition, although it still costs the same as before. This reward has a bug where, when the player loads a 100% saved game, all the ammo that was over the original limit is gone. Also, after killing 200 Flying Rats an Annihilator spawns on a helipad in Star Junction, although it seems to spawn randomly.
